The role of the hydrological cycle on the temporal patterns of macroinvertebrate assemblages in an Andean foothill stream in Colombia

Abstract

The

Hydrological cycle effects on the aquatic community in a Neotropical stream of the Andean piedmont during the 2007–2010 ENSO events

“…The taxonomic compositions of the assemblages and their respective functional categories are described in Ríos‐Pulgarín et al . (, ), M. I. Ríos‐Pulgarín, M. Barletta, I. C. Gil‐Guarín & N. J. Mancera‐Rodríguez (unpubl. data) and in Tables II–V.…”

“…The functional feeding groups (FFGs) and life habits of macroinvertebrates were those proposed by Ríos‐Pulgarín et al . (). The assignment of the functional groups of macroinvertebrate taxa was based on a review of Merritt & Cummins (), Tomanova et al .…”

“…It is subject to tropical rainforest conditions with precipitation exceeding 3800 mm year −1 , temperatures of above 25° C and humidity between 60 and 80% (Holdridge, ), and its soils are of volcanic origin (Borrero, ). The hydrological regime is bimodal and has a rapid transition between the high zone and the alluvial plain, with periodic flooding events (Ríos‐Pulgarín et al ., , ; M. I. Ríos‐Pulgarín, M. Barletta, I. C. Gil‐Guarín & N. J. Mancera‐Rodríguez, unpubl. data).…”

“…The identification of organisms was performed at the lowest taxonomic level possible using specialized keys for fish species and macroinvertebrate and algae genera (Ríos‐Pulgarín et al ., , ; M. I. Ríos‐Pulgarín, M. Barletta, I. C. Gil‐Guarín & N. J. Mancera‐Rodríguez, unpubl. data).…”
